Try running the following to see if you run into any errors.

python3
import matplotlib.pyplot

mport matplotlib.pyplot

Run in your terminal and see if you can import matplotlib yourself:

python3
import matplotlib.pyplot

Feel free to reopen if the above commands ran successfully, and you still had the problem.
